Shutdown due to low battery
Problem
When the power is turned on or off or during
execution of programs (System Mode or
applications), the battery output level has lowered
to the extent the BHT can no longer operate.
If lower battery is detected, the BHT beeps
five times (for 0.1 second per beep) and
then turns itself off. Depending upon the
battery level, the beeper may not sound five
times.
Solution
Replace or recharge the battery cartridge.
If the grip style BHT is loaded with battery
cartridges both in the BHT body and the grip,
replace or recharge both battery cartridges. Always
remove both battery cartridges, even if you only
have one fully-charged replacement battery
cartridge on hand.
Service life warning for backup battery
Problem
The backup battery has been charged/discharged
by the specified number of times so that the battery
capacity lowers below the specified level.
Solution
Replace the backup battery. For the replacement
procedure, refer to the User's Manual.
